Method Detail

getOwnerReplicaOrNull

PartitionReplica getOwnerReplicaOrNull()

Returns:

the owner

getReplicaIndex

int getReplicaIndex(PartitionReplica replica)

Return the index of partition replica for this partition.

Parameters:

replica - partition replica

Returns:

the replica index or -1 if the replica is null or the replica is not in the replica list

getReplica

PartitionReplica getReplica(int replicaIndex)

Returns the partition replica assigned to the replica index.

The owner has replica index 0.

The returned value could be null if the owner/replica has not yet been set.

The returned value could be stale when it is returned.

Parameters:

replicaIndex - the index of the replica

Returns:

the partition replica

Throws:

ArrayIndexOutOfBoundsException - when replica index is out of bounds
